NV Energy Begins Mass Deployment of EcoFactor

REDWOOD CITY, CA –(Marketwire –Nov. 13, 2012) EcoFactor®, the leader in cloud-based
software services for home energy management, today announced that NV Energy, Inc. has
begun mass deployment of the EcoFactor service under the NV Energy mPowered brand.

The integrated demand side management partnership calls for EcoFactor to deliver both
double-digit energy savings to consumers, and a minimum of 20 megawatts of load
reduction in the Las Vegas market during the first phase of deployment. Additional phases
are also planned.

The launch of the NV Energy mPowered solution with EcoFactor stems from the success of a
pilot program in the Las Vegas metropolitan areas. Results of measurement and verification
studies conducted by NV Energy during this pilot showed that the EcoFactor service
simultaneously:
• Saved an average of 13 percent of customer cooling costs during a scorching Las
Vegas summer.
• Delivered an average demand response load reduction of more than 3 kilowatts per
home on NV Energy’s benchmark measurement & verification days, which is
significantly higher than NV Energy has achieved using other approaches.

EcoFactor's patented, cloud-based energy service analyzes a home’s specific heating and
cooling system information, thermostat settings, personal preferences, indoor temperatures,
local weather conditions and several other behavioral factors. Using an Internet-enabled
thermostat, the EcoFactor service continually learns and adapts to these factors,
automatically making small adjustments to thermostat settings throughout the day to
reduce energy consumption and shift energy use without compromising comfort. EcoFactor helps residents heat and cool their homes more efficiently, saving money on their utility
bills. The service helps leading-edge utilities like NV Energy maintain customer comfort
while effectively managing demand-side impact on the grid.

“The broad availability of our service with NV Energy is further validation that EcoFactor
delivers value for large utilities,” said Roy Johnson, CEO, EcoFactor. “With EcoFactor,
homeowners stay comfortable during demand response events without giving up control of
the temperatures in their homes. We are helping utilities move into a new era where they
achieve their business goals while delivering tangible benefits to customers.”

NV Energy, which provides electricity to 2.4 million Nevadans, began rolling out its
mPowered solution with EcoFactor to Las Vegas residents in October. To sign up for the
